Why Magento won’t allow you to show out of stock options in configurable products is beyond me, thankfuly nyah, on the Magento forums was kind enough to post a “quick-fix” for this delima, first edit:

app/code/core/Mage/Catalog/Block/Product/View/Configurable.php

locate the getAllowProducts() function…

public function getAllowProducts()
    {
        if (!$this->hasAllowProducts()) {
            $products = array();
            $allProducts = $this->getProduct()->getTypeInstance()->getUsedProducts();
            foreach ($allProducts as $product) {
                if ($product->isSaleable()) {
                    $products[] = $product;
                }
            }
            $this->setAllowProducts($products);
        }
        return $this->getData('allow_products');
    }

and replace or comment out the existing method with:

public function getAllowProducts() {
        $allProducts = $this->getProduct()->getTypeInstance()->getUsedProducts();
        $this->setAllowProducts($allProducts);
        return $this->getData('allow_products');
    }

Looking at the above fix basically all products in the configurable product are displayed regardless of their isSaleable() state. Which I’m assuming a better solution would be to modify it instead in case of other instances not just out of stock.

This won’t disable the product out the option but if a user attempts to order it will get an out of stock message. Its not perfect but serves the purpose until Magento can possibly make a more permanent solution.

Be aware this modifies the Core code of magento and its highly recommended that you make a backup of the Configurable.php file before modifying its contents.
